Python AesEaxKey Examples

Example #1

File: aead_consistency_test.py Project: yangboyd/tink

 def _test_case(key_size=16, iv_size=16, key_version=0):
     key = aes_eax_pb2.AesEaxKey()
     key.version = key_version
     key.key_value = _gen_key_value(key_size)
     key.params.iv_size = iv_size
     keyset = _gen_keyset(
         'type.googleapis.com/google.crypto.tink.AesEaxKey',
         key.SerializeToString(), tink_pb2.KeyData.SYMMETRIC)
     return ('AesEaxKey(%d,%d,%d)' % (key_size, iv_size, key_version),
             keyset)
